How to Reconstitute SS-31
Updated today
SS-31 is supplied as a 50 mg lyophilized (freeze-dried) vial and must be reconstituted with bacteriostatic water before use. Adding 2 mL to a 50 mg vial yields a concentration of 25 mg/mL — so a 250 mcg reference dose is 1 units on a standard U-100 insulin syringe. Use more water for a more dilute, easier-to-measure solution, or less for a more concentrated one; the amount of compound in the vial is the same either way. Adjust the calculator below to match your exact vial size and target dose.
| Dose | Units (U-100) | Volume |
|---|---|---|
| 250 mcg | 1 units | 0.01 mL |
| 500 mcg | 2 units | 0.02 mL |
| 1000 mcg | 4 units | 0.04 mL |
| 2000 mcg | 8 units | 0.08 mL |
